    From Single Cells to Complex Creatures: New Study Points to Origins of Animal Multicellularity

    Newswise — Animals, from worms and sponges to jellyfish and whales, contain anywhere from a few thousand to tens of trillions of nearly genetically identical cells. Depending on the organism, these cells arrange themselves into a variety of tissues and organs, such as muscles, sensory systems, or the gut. While not all animals have each of these tissues, they do all have one tissue, the germline, that produces sperm or eggs to propagate the species.

    Scientists don’t completely understand how this kind of multicellularity evolved in animals. Cell-to-cell adhesion, or the ability for individual cells to stick to each other, certainly plays a role, but scientists already know that the proteins that serve these functions evolved in single-celled organisms, well before animal life emerged.

    Now, research from the University of Chicago provides a new view into key innovations that allowed modern, multicellular animals to emerge. By analyzing the proteins predicted from the genomes of many animals (and close relatives to the animal kingdom), researchers found that animals evolved a more sophisticated mechanism for cell division that also contributes to developing multicellular tissues and the germline.

    “This work strongly suggests that one of the early steps in the evolution of animals was the formation of the germline through the ability of cells to stay connected by incomplete cytokinesis,” said Michael Glotzer, PhD, Professor of Molecular Genetics and Cell Biology at UChicago and author of the new study. “The evolution of three proteins allowed both multicellularity and the ability to form a germline: two of the key features of animals.”

    Positioning the division plane

    Cell division, or cytokinesis, is the process by which a cell divides into two distinct daughter cells. Many of the proteins involved with cytokinesis are ancient, present long before the first Metazoa arose about 800 million years ago.

    Glotzer has been studying animal cell division for several decades, focusing on how cells determine where to divide. In animal cells, a structure called the mitotic spindle segregates the chromosomes before the cells divide; it also dictates the position where cell division occurs. Glotzer and his team homed in on a set of three proteins—Kif23, Cyk4, and Ect2—that bind to each other and the spindle, and which are directly involved in establishing the division plane. Close relatives of these proteins had only been found in animals previously.

    Two of these proteins, Kif23 and Cyk4, form a stable protein complex called centralspindlin that Glotzer and his colleagues discovered more than 20 years ago. Not only does centralspindlin contribute to division plane positioning, but it also generates a bridge between the two incipient daughter cells.

    The cells that make up non-germline tissues and organs are called somatic cells, which are not passed on to the next generation. Germline cells are special because they can become any cell type. During the development of sperm and eggs, these cells also recombine the chromosomes they inherited from their parents, generating genetic diversity. While centralspindlin-dependent bridges are generally severed in somatic cells, the germlines of most animals have cells that remain connected by stable bridges.

    Tracking down the proteins

    Given the recent explosion in genome sequence data now available for a wide range of animals, Glotzer first wanted to determine if the two proteins that make up the centralspindlin complex, as well as Ect2, the regulatory protein that binds to it, were present and well conserved in all animals. During his analysis for this study, which was published in Current Biology, he found that all branches of animals have all three of these proteins.

    Studies of these proteins in species commonly used in the lab discovered common patterns that are linked to their known functions. Using Google DeepMind’s AlphaFold AI platform (developed by UChicago alum and recent Nobel Laureate John Jumper), Glotzer was able to predict the interactions among these different proteins and found that every interaction is likely conserved across all animals. This suggests that these proteins were all in place at the beginning of the animal kingdom more than 800 million years ago and have not undergone any dramatic changes since that time.

    Next, Glotzer wondered whether any related proteins could be found in single-celled organisms. He identified somewhat related proteins in choanoflagellates, the group of single-celled creatures most closely related to animals. Alphafold predicted that some of them can form a complex somewhat like centralspindlin. Though related, these complexes are clearly distinct from centralspindlin, and they lack the sequences that allow Ect2 to bind to the structure. Remarkably, some choanoflagellate species that have this complex can form colonies via incomplete cytokinesis too.

    “Pre-metazoan cells have mechanisms of dividing and separating, probably with some themes and variations. Then this protein complex allowed cells to stop at the stage just before separation,” Glotzer said. “Maybe multicellular life evolved because of a genetic change that prevented cells from fully separating.”

    “A mutation that disrupted the assembly of centralspindlin is what allowed my colleagues and me to find these proteins in the first place, more than 25 years ago,” he continued. “And it appears that the evolution of this exact same region contributed to the evolution of animal life on the planet, which is mind blowing.”

    The study, “A key role for centralspindlin and Ect2 in the development of multicellularity and the emergence of Metazoa,” was supported by the National Institutes of Health.

  • ‘Project Hail Mary’ trailer: Ryan Gosling goes to space, meets alien

    ‘Project Hail Mary’ trailer: Ryan Gosling goes to space, meets alien

    Ryan Gosling puts the “not” in “Astronaut” in the new trailer for “Project Hail Mary.”

    The upcoming sci-fi film, based on Andy Weir‘s novel of the same name, stars Gosling as middle school teacher turned reluctant astronaut Ryland Grace, who’s tasked with saving humanity from the effects of a dimming sun. However, when he wakes up from a coma as the sole survivor aboard a spaceship, he must overcome his amnesia to remember where he is and why he was sent there.

    “It’s an insanely ambitious story that’s massive in scope and it seemed really hard to make, and that’s kind of our bag,” Gosling said of “Project Hail Mary” at CinemaCon in April, where he debuted footage from the film, according to Variety. “This is why we go to the movies. And I’m not just saying it because I’m in it. I’m also saying it because I’m a producer on the film.”

    The trailer, released Monday by Amazon MGM Studios, opens with Gosling startling awake on the spacecraft, his hair and beard uncharacteristically long. “I’m several light-years from my apartment,” he proclaims, “and I’m not an astronaut.”

    It then jolts back in time to show Grace pre-launch as he learns from Eva Stratt (Sandra Hüller) that if he does not journey into space, everything on Earth will go extinct. According to Stratt, who heads the mission, Grace is the only scientist who might understand what is happening to the sun and surrounding stars.

    The trailer, which progresses through an intense montage set to Harry Styles’ “Sign of the Times,” teases Gosling’s signature humor. “I can’t even moonwalk!” the “Barbie” actor declares at one point. (Gosling portrayed moonwalker Neil Armstrong in another recent space movie, Damien Chazelle’s “First Man.”)

    Everything leads up to Grace meeting an alien, who isn’t shown in full — but fans of the book know it plays an integral role in saving planet Earth and beyond.

    The film, directed by Phil Lord and Christopher Miller, marks the second book-to-movie adaptation for Weir, whose novel “The Martian” became an Oscar-nominated 2015 blockbuster starring Matt Damon. An adaptation for his book “Artemis” is also in development with the same directing team.

    “Project Hail Mary” hits theaters March 20.

  • Steam can now show you how much frame generation changes your games

    Steam can now show you how much frame generation changes your games

    Valve has added a new performance monitor to Steam that can help you understand why a game may or may not be running smoothly. Not only does it break out a game’s overall frame rate, it can tell you how many of those frames were generated by techniques like Nvidia’s DLSS or AMD’s FSR, according to a post.

    The change is included as part of an update to the Steam Client that’s available now, though Valve notes that this “first version” focuses on “Windows users and on the most common GPU hardware.”

    The company says the new performance monitor currently offers up to four different levels of detail: a single FPS value, FPS details, CPU and GPU utilization, and “FPS, CPU, GPU & RAM Full Details.” The more you choose to show, the more of your screen will be taken up by the performance monitor.

    Steam previously offered a simple FPS counter, but separating out generated frames from the frames fully rendered by your graphics cores can help you better understand key differences between what you see and how a game feels. “Frame generation can’t help with things like input latency that matter to competitive gamers, but it can make things look visually smoother on today’s high refresh rate monitors,” Valve says in a detailed support document about the performance monitor.

    In practice, what that should mean is that you can see whether your game feels like it’s running at just 30 fps because it actually is running at 30 fps inside the game engine, even though you’re seeing a visually smoother image due to Nvidia and AMD’s added “fake frames.” (It’s a whole debate in the PC gaming community, and it appears Valve isn’t taking sides here.)

    Valve has already given handheld gamers a taste of these quick insights by building tools like MangoHud into the Steam Deck and SteamOS, which similarly let you monitor your CPU, graphics, RAM, and carefully ration out your battery life. But having a way to do so built into desktop Steam will make the insights much more accessible to many more gamers.

    In the future, Valve says that it has plans to “add some additional pieces of data to the performance overlay going forward, to detect certain common bad hardware performance scenarios, and to show a larger summary of your game’s performance in the overlay itself when you hit shift-tab.”

  • Aamir Khan’s big screen comeback, Sitaare Zameen Par, features an all-star neurodivergent cast – a Bollywood first

    Aamir Khan’s big screen comeback, Sitaare Zameen Par, features an all-star neurodivergent cast – a Bollywood first

    Bollywood star Aamir Khan’s return to the big screen after a three-year hiatus has been far from ordinary. Sitaare Zameen Par (2025) which translates to “stars on Earth”, is the first major Bollywood production to feature a mostly neurodivergent cast.

    A remake of the 2018 Spanish film Campeones, the story follows a mouthy, knuckle-headed basketball coach, Gulshan (Aamir Khan), who is put in charge of a team of players with intellectual disabilities.

    The film slowly grows into itself, much like its characters, but ultimately delivers what the trailer promises: a heartwarming, humorous and uplifting celebration of our individual differences.

    In an era of blockbuster spectacles, Aamir Khan Productions brings back a kind of Bollywood storytelling we haven’t seen in a while – something sincere, gentle and quietly revolutionary.

    Who is Aamir Khan?

    Aamir Khan was born in Mumbai in 1965, and started his acting career as a child actor in his uncle’s film Yaadon Ki Baaraat (1973).

    Khan is now one of Bollywood’s most enduring and respected figures. He is one of the iconic “three Khans”, alongside Shah Rukh Khan and Salman Khan (the three are unrelated), who have dominated Indian cinema since the 1990s.

    Film stars Aamir Khan, Salman Khan and Shah Rukh Khan are dubbed the ‘three Khans’ of Bollywood.
    AP

    But unlike his Khan counterparts, Aamir Khan has carved a unique career path built on both commercial success and socially-driven storytelling.

    He is known for championing social causes through cinema. In one 2015 article, media studies professor Vamsee Juluri referred to him as a “national conscience figure”.

    Khan’s films don’t just entertain; they challenge norms and often spark national conversations on important issues.

    From producing Lagaan: Once Upon a Time in India (2001), India’s Oscar-nominated colonial-era sports epic, to his directorial debut Taare Zameen Par (2007), a moving portrait of a child with dyslexia, Khan’s work often brings underrepresented stories to the mainstream.

    Lagaan follows farmers from a small Indian village under British colonial rule. The British challenge the farmers to a game of cricket, in exchange for an exemption from paying the land tax (‘lagaan’).
    IMDb

    His film PK (2014) challenges religious dogma. Meanwhile, Dangal (2016) is a boundary-pushing film based on real-life female wrestlers from rural India, and is also Bollywood’s highest-grossing film of all time.

    Beyond the box office, Khan has hosted the TV show Satyamev Jayate (2012–14), which is also the national emblem of India, meaning “truth alone triumphs”.

    This show tackles various topics considered taboo in Indian societies, including female feticide, domestic violence and caste discrimination. It has reached millions of households, and even ignited parliamentary debates.

    Khan is also popular in other countries, including China, where his films 3 Idiots (2009), Dangal (2016) and Secret Superstar (2017) were massive hits that resonated with audiences for their universal themes.

    In Dangal (2016), Mahavir (Aamir Khan) trains his two daughters in wrestling.
    IMDb

    Sitaare Zameen Par marks his return following the commercial underperformance of Laal Singh Chaddha (2022), an Indian remake of Forrest Gump (1994).

    Sitaare (stars) who make the film shine

    Directed by R.S. Prasanna, Sitaare Zameen Par enjoyed a strong opening weekend at the box office.

    It stars ten individuals with special needs as they prepare for a basketball tournament under the direction of their coach (Khan). This plot alone makes the film a significant entry to Indian cinema, which often ignores or misrepresents disability.

    The neurodivergent stars of Sitaare Zameen Par are aged between 18 and 42.
    Aamir Khan Productions.

    Despite early online trolling and negativity, the film depicts its neurodivergent characters not as victims, or “inspirations”, but simply as people with dreams, struggles and joy.

    One line captures this beautifully: “Everyone sticks to their own normal. We each have our own normal.”

    Aamir Khan, now 60, plays a key role in the film, but doesn’t dominate it. Instead, his younger co-stars shine. The result is a healing film that celebrates inclusion, while being full of joy and humanity.

    Stories that matter

    No film is perfect. But it’s hard to dislike a film made with so much compassion.

    Bollywood as an industry has increasingly leaned into action-packed blockbusters, as well as nationalist and Hindu-centred narratives (such as in the 2022 film Brahmāstra).

    While many of these offer thrills, few deliver the kind of emotional and social depth that once defined Hindi cinema’s global appeal. Much like Taare Zameen Par – a spiritual prequel to the new release – did 18 years ago, Sitaare Zameen Par invites the audience to slow down and reflect.

    In Taare Zameen Par (2007), Khan plays a neurotypical teacher who helps a student with dyslexia.
    IMDb

    It prompts neurotypical viewers to see people with Down’s syndrome as part of the same emotional universe as them – and to laugh with, not at them.

    In an interview, Khan explains how the film goes further than just neurodivergent representation, to participation:

    In [Taare Zameen Par], it’s the teacher, Nikumbh, a supposedly neuro-typical person, who helps the child with dyslexia. In this film, ten neuro-atypical people are helping the coach, Gulshan. I feel Sitare takes the discourse of the first film ten steps ahead, especially in our country where people need to be sensitised to the topic of neurodivergence.

    Last week, India’s president, Droupadi Murmu, attended a special screening and met the cast. The visit sent a clear messsage: stories like this matter.

    With Sitaare Zameen Par, Aamir Khan returns to what he does best: using film as both a mirror and message for Indian society. While it won’t change the world overnight, it will make viewers see the world, and each other, a little differently.

  • Force farewells six players after conclusion of 2025 season

    Force farewells six players after conclusion of 2025 season

    The Western Force thanks departing players Ryan Coxon, Tom Horton, Atu Moli, Reesjan Pasitoa, Matt Proctor and Sio Tomkinson for their service to the Club.

    The departure of the sextet comes after Saturday’s tour game against the British and Irish Lions following the conclusion of the 2025 Super Rugby Pacific season.

    The Club acknowledges their contributions and service, wishing them all well for the future. They are forever Force.

    Coxon, 27, spent two seasons with the Force, joining the Club in the 2024 season on an injury cover contract. The affable loosehead prop played 19 Super Rugby games for the Force.

    Horton joined the Force prior to the 2023 season and started every game in the 2024 season. The tough 28-year-old hooker played 34 Super Rugby games for the Force across three campaigns.

    Former All Blacks front-rower Moli, 30, spent two years at the Force, overcoming a significant hip injury in his first season to play 10 games off the bench in the 2025 Super Rugby season.

    Homegrown utility back Pasitoa joined the Force in 2022 after a stint with the ACT Brumbies. He played 20 Super Rugby games for the Force, having missed the 2023 and 2024 seasons due to significant injuries before making a return in 2025. The Club have released him early at his request in order to play NPC in New Zealand.

    One-cap All Blacks midfielder Proctor joined the Force prior to the 2025 Super Rugby season but missed the whole campaign with a shoulder injury, before running out in Force blue for the first time in Saturday’s Lions game.

    Tomkinson also joined the Force prior to the 2025 Super Rugby season. The 29-year-old New Zealand-born midfielder played 10 games, all starts, and scored one try.

  • ‘They came for our land, our wood, our gold’: Santiago Yahuarcani, Peruvian painter of dancing dolphins – and genocide | Art and design

    ‘They came for our land, our wood, our gold’: Santiago Yahuarcani, Peruvian painter of dancing dolphins – and genocide | Art and design

    Santiago Yahuarcani’s Amazon is no longer the place he painted as a child. The rainforest scenes of parrots, anacondas and jaguars that he and his brothers used to sell to riverboat tourists for a dollar apiece have given way to visions of a landscape that is darker, more despoiled and more desperate than it was six decades ago.

    However, as his first solo international exhibition – at the Whitworth in Manchester – will show, the old beauties and mysteries have not faded completely. His work is populated by shape-shifting spirits, mermaids waltzing with pink river dolphins, enormous pipe-smoking lizards and shamans who trap their adversaries in rum bottles, but they exist alongside depictions of the genocidal crimes of the past and the ecocidal crimes of the present. Oil refineries are consumed by fire, rubber trees weep tears of sap, forest spirits are displaced by drought, and memories of a century-old slaughter – replete with torn and branded flesh – echo through the forest and down the generations.

    “When I was a child, there was a huge abundance of animals and fish in the Amazon,” says the 65-year-old Indigenous Peruvian painter, when we meet in Madrid, at a joint exhibition of work by him and his partner Nereyda López. “There was a lot of land to make into farmsteads and there were a lot of animals to hunt. But people have come and taken land – hectares of land, kilometres of land – and they’ve come for the wood and the gold, too.”

    The artist and his family are all too aware of what happens when the Amazon attracts the greedy gaze of the outside world. Today, they are the last 12 members of the White Heron clan of the Uitoto nation still living in Peru. Just over a century ago, Yahuarcani’s grandfather, then 16, was forced from Colombia to Peru during the genocide that was waged against the Indigenous population of the Putumayo region during the rubber boom. The painter was five or six when he learned what had happened at La Chorrera rubber station.

    “My grandfather would call us together at night and tell us about the era of rubber,” he says. “He told us how the bosses arrived with rifles and started to force the Indigenous people to collect the sap of trees for rubber. They demanded 50kg of sap from each person every two to three weeks. They gave them the materials they needed to get the sap and they gave them food, but not enough food.”

    Anyone coming back with less than 50kg was punished. Some were thrown into a hole​ 15 metres deep. Others had an ear hacked off. “There was also a guy, my grandfather told me, who’d make everyone watch​ as he cut off a lump of your fles​h with a knife. They wanted to scare people so they’d get their 50 kilos.”

    Then came the time when the bosses decided to plant sugar cane, coffee and corn for the women to harvest. “These women worked with their babies on their backs,” says Yahuarcani. “One baby started to cry because of the heat of the sun. The overseers came and took the little boy from his mother’s back and threw him on the fire.​”

    When the inevitable uprising took place, the response was characteristically barbaric. Men, women and children were burned alive in a large house where they had sought refuge. Those who escaped the flames were shot. “My grandfather told me that, a month after the fire, thousands of butterflies of a kind never before seen in the Amazon began to sprout from the site,” says Yahuacari. “All different kinds of butterflies with all different kinds of colours. My grandfather told me they were the spirits of the victims, of the people who had been burned.”

    Those atrocities are recounted in one painting – called The Stone-Hearted Man – that shows gangs of pale men in white hats and with pistols in their belts branding, decapitating and burning their way across a stretch of rainforest that has become a hell. All around them are the charred and broken bodies of Indigenous people.

    A century later, the rainforest is once again besieged. “Today, Indigenous groups are having to fight back,” says Yahuarcani. “We have to fight to protect our vegetation, our trees and to reforest.” But the odds are not in their favour. While more and more outsiders are coming to the Amazon in search of land, timber, gold and oil, many of the region’s young people are abandoning their homes in search of education and employment. Respect for the rainforest is dwindling.

    Whenever they set out to hunt or fish, the Uitoto make an offering to the guardian of the forest animals: “He’s small and furry like a monkey and has the face of an 80-year-old person.” And, unlike the logging and mining corporations, they never take more than they need. “In the Amazon,” he says, “when we want to eat, we go to our supermarket – it’s in the mountains, in the jungle, where there are fish and fruits. You bring home what you need and you don’t destroy everything. God has said that man should not destroy nature, he should take care of it, because it is his home, too. You can’t destroy your own house.”

    If the artist’s subject matter has changed over the years, his techniques have not. Yahuarcani has always created his works by applying paint prepared from pigments, seeds, leaves and roots, to large sheets of llanchama, a cloth made from the bark of the ojé tree. His works are often inspired by the hallucinations brought on by the ritual ingestion of tobacco, coca, ayahuasca and mushrooms – substances long used by the Indigenous peoples of the Amazon when in search of help, knowledge or revelation.

    While getting llanchama requires the skills he learned from his bark-cutter grandfather, the use of hallucinogens harnesses and honours the cosmology, myths and traditions of Yahuarcani’s people as he strives to draw attention to the threats they and the forest face. Perhaps the greatest of those menaces is indifference. Yahuarcani’s home town of Pebas, which lies on a bend in the river as it meanders from north-east Peru towards Colombia, is as far removed as it could be from the artistic, political and media centres of the coastal capital, Lima. As a result, getting his work and its messages noticed has been a struggle.

    Yahuarcani is polite but insistent as he reflects on the difficulties that he and other Indigenous artists – not least his son Rember – experience when it comes to visibility and exhibition space. “I use my work to show our myths,” he says. “How our culture used to be, how we came to have the problems we now have. But it’s been very tough because we were from the Amazon and we were Indigenous. We weren’t allowed to exhibit in the museums, or do the interviews, because we were always put to one side.” Artists from Lima “have always had more opportunities and more press”.

    Part of the problem, he says, lies in Peru’s own view of its culture and history. “When we were in school, we were taught about the Incas. About how the Incas built Machu Picchu, and so on. But there was nothing about us or our history, and that’s been one of our complaints. Our stories aren’t in the textbooks.” Yet he is adamant that this is a history people need – and want – to know about. When he exhibited a picture of the Putumayo atrocities in Lima ​a decade ago, “the newspapers and the magazines were saying, ‘Look at this! Look at this!’ But the authorities were not at all interested.”

    Yahuarcani has been buoyed by the enthusiastic reaction to the Madrid show – even if it has meant braving the heat and chaos of the Spanish summer. He hopes the Manchester exhibition will be equally well received. But the recognition has been as hard won as it has been belated. Time is running out and, as one of his recent works plainly shows, the Amazon is changing rapidly and irrevocably. Painted earlier this year, Optic Fibre in the Depths of the Amazon River is a riotous, funny and faintly disturbing picture that shows dolphins, frogs, fish and turtles clutching mobile phones as technology reaches ever farther into the rainforest. One or two of the smarter fish are ringing their friends to let them know where the fishers are gathered so they can avoid them.

    The current cycle of expansion, encroachment and exploitation appears unstoppable. And if the forest goes then so does a branch of the Uitoto, their way of life, and their half-forgotten history. “I hope Peru will do something about these issues,” says Yahuarcani. “That there will be a book of these stories so young people can learn what happened to their grandparents. Today, we are the only family of the White Heron clan. There are no more. When we disappear, the White Heron ends.”

    Santiago Yahuarcani: The Beginning of Knowledge is at the Whitworth, Manchester, 4 July to 4 January; part of Manchester International Festival, 3-20 July.

  • New Species of Permian Herbivorous Tetrapod Identified in China

    New Species of Permian Herbivorous Tetrapod Identified in China

    Paleontologists have identified a new genus and species of mid-sized pareiasaur from two fossilized specimes found in China in 2018.

    Named Yinshanosaurus angustus, the newly-identified species roamed Earth during the latest Permian period, between 259 and 254 million years ago.

    The ancient beast was a member of Pareiasauria, a specialized group of herbivorous tetrapods that existed throughout the supercontinent Pangea during the Middle-Late Permian.

    “Pareiasauria are a bizarre herbivorous clade of tetrapods that existed in the Guadalupian and Lopingian and were victims of both the Late Capitanian and the end-Permian mass extinction events,” said Dr. Jian Yi and Jun Liu from the Institute of Vertebrate Paleontology and Paleoanthropology at the Chinese Academy of Sciences, the University of Chinese Academy of Sciences, and Chongqing Institute of Paleontology.

    “Pareiasauria has a worldwide distribution, with fossils discovered in Africa, Europe, Asia and South America.”

    “Pareiasaurs were common primary consumers in several terrestrial tetrapod faunas, including the Late Permian fauna of northern China.”

    “Since the 1960s, eight Chinese pareiasaur species have been described.”

    Two specimens — a nearly complete skull and an articulated partial postcranial skeleton with a nearly complete skull — were unearthed in China in 2018.

    “The first specimen was excavated form the dark purple siltstone in the lower part of the Sunjiagou Formation, near Zhangjiagetuo village, Baode county, Xinzhou city, Shanxi,” the paleontologists said.

    “The second specimen was excavated from purplish silty mudstone in the upper part of Member I of the Naobaogou Formation, near Qiandian village, Shiguai district of Baotou City, Nei Mongol.”

    According to the authors, Yinshanosaurus angustus had the narrowest skull of all pareiasaurs, with skull length more than twice the skull width at the lateral edges of the cheeks.

    “The skeleton of Yinshanosaurus angustus provides the complete cranial and articulated postcranial details of Chinese pareiasaurs for the first time,” they said.

    Their paper was published this month in the journal Papers in Palaeontology.
